Product effect
Proanthocyanidins are the general name of a large class of polyphenols widely found in plants. They have strong antioxidant and free radical eliminating effects, and can effectively eliminate superoxide anion free radicals and hydroxyl free radicals. They also participate in the metabolism of phosphoric acid and arachidonic acid and protein phosphorylation, and protect lipids from peroxidation damage.
It is a powerful metal chelating agent, which can chelate metal ions and form inert compounds in the body.
Protect and stabilize vitamin C, help the absorption and utilization of vitamin C.
Proanthocyanidins are widely distributed in the skins, shells, seeds, cores, flowers and leaves of many plants, and grape seeds have the highest content of proanthocyanidins and rich species.

 

Advantages:

There is a complete production line. Stable and high-quality raw material sources. Mature and stable production process. The product solvent residue is qualified. A variety of product specifications are available. It can be stored for a long time in a cool, dry place and sealed away from light.
Safety:

As a food additive and plant extract, it is safe, non-toxic and harmless.

Efficacy:
Grape seed extract is a kind of polyphenols extracted from grape seeds, mainly composed of proanthocyanidins, catechins, epicatechin, gallic acid, epicatechin gallate and other polyphenols.

Storage :
Store in a cool, dry, dark, and high-temperature place.

Packaging :
Negotiate or use double-layer plastic bags, 1kg aluminum foil bags, and 25kg cardboard barrels internally.

The main pharmacological effects are as follows:
1. Antioxidant effect:
The polyphenols in grape seed extract include proanthocyanidins and gallic acid phenolic hydroxyl groups, which provide hydrogen atoms and have specific and powerful antioxidant effects. The ability to neutralize iron ions and oxygen that attack lipids is 15 to 25 times that of VB, and its free radical scavenging effect is stronger than antioxidants such as VC and VE.
2. Anti-radiation effect:
Can inhibit radiation-induced lipid peroxidation.
3. Anti-inflammatory effect:
The main components are proanthocyanidins, whose antioxidant activity can inhibit the synthesis and release of inflammatory factors such as histamine, 5-hydroxytryptamine, prostaglandins and leukotrienes, inhibit the release of granules from basophils and mast cells, and also inhibit the synthesis of Amine decarboxylase activity limits the action of hyaluronidase.
4. Preventing cataracts:
The main component for preventing cataracts is catechin; grape seed extract can improve the vision of patients with myopic non-inflammatory retinal changes and improve eye fatigue.
 

 

5. Anti-cancer effect:
It is cytotoxic to MChemicalbookCF-7 human breast tumor cells, A-427 human lung cancer cells and CRL1739 human gastric adenocarcinoma cells, and can prevent the carcinogenic effects of intestinal chemical carcinogens.
6. Anti-atherosclerotic effect:
Foods containing 2.5% grape seed extract can reduce cholesterol ester peroxide levels in the serum of experimental animals and can also reduce low-density lipoprotein to fight atherosclerosis. It can improve blood rheology indicators and platelet aggregation.
7. Cholesterol-lowering effect:
Gallic tannins can reduce plasma total cholesterol, triglycerides, low-density cholesterol and very low-density cholesterol levels, and increase high-density cholesterol levels.
8. Anti-ulcer effect:
The oligomeric proanthocyanidins in grape seed extract can protect gastric mucosal damage. Proanthocyanidins have the effect of scavenging free radicals on the gastric surface and protecting the gastric wall.
9. Anti-mutagenic effect:
It can reduce the incidence of mitochondrial mutations and nuclear mutations.
